A method and apparatus for the stabilizing of napthopyran and spiroxazine photochromic dye in a coating or plastic media is presented. As prolonged exposure to light causes degradation of the photochromic properties of the dyes, a two-tiered layering system is utilized in which a hindered amine stabilizer (HALS) and / or an ultraviolet light (UV) absorber, is placed as a clear coat layer above a bottom layer containing the photochromic dyes. The bottom layer is constructed containing the photochromic dyes by either a coating of a surface of a lens or an imbuing of the photochromic dyes into the lens material, and can further optionally contain a HALS and / or UV blocking compound itself.

An improved plunger mechanism apparatus has an internal shock absorber to increase plunger life and increases life of components found at a top and well bottom. The internal shock absorber can be an elastomer spring, die coil spring or wave spring. An actuator rod within the plunger hits the bottom of the well and compresses the internal spring, absorbing all or part of the impact shock. Likewise, when a plunger rises to the well top with a high velocity, damage is avoided as the top of the plunger hits well top apparatus. Reduction in well bottom bumper spring collapses, spring damage, and plunger damage is obtained. Damage to well bottoms having no bumper springs is avoided. Efficiency of well flow is increased by the increase in the reliability of the well operation.

The present invention pertains to a method of determining a working voltage of an inverter, which utilizes a rectifying method to transform an alternating current into a pulse direct current, and then via a working frequency, divides a direct current cycle, which ranges in a lowest voltage—highest voltage—lowest voltage manner, into multiple continuous voltage pulses. The inverter receives each one of the multiple continuous voltage pulses and acts in response to each one of the multiple continuous voltage pulses and corresponding to the voltage cycle ranging between the lowest voltage and the highest voltage to output a variable voltage signal to a load. Thus, the working voltage of the inverter is analogous to the input voltage of the alternating current, and a power-factor regulating effect can be accomplished directly by the inverter.
